Booah thanks for the fast answer :D New to all the things here - i'm so sorry! Next question i got! After i remover the roleFunction from the listRoleFunctions (i've checked, it's okay) and save the removed item is still available in the database! Bad news: there's no stack trace neither in console nor server.log! Hope this issue is as simple to solve as the last one =) Thanks for your assistance!
